Problems solved by technology

The instrument disinfectant mainly uses 1) glutaraldehyde at present, but glutaraldehyde has a strong irritating smell and needs to be kept ventilated; Strongly corrosive; 2) oxychloraz is corrosive, can penetrate organic substances, has a good disinfection effect, and has a short action time (3 minutes). At present, it is used more on medical devices such as endoscopes, but because The chlorine-containing component is also a strong corrosive liquid, which cannot be used for washing hands, etc., and it will cause damage to the equipment after a long time
3) Acidified water is mainly used for disinfection, not as a sterilizing agent, and it is not as good as oxychloraz and glutaraldehyde. However, in clinical use, due to the unstable acidified water generated, ① cannot reach the oxidation-reduction potential; ② always maintain pH2 .7-2.8, 2 O, no disinfection effect, when the endoscope contains blood stains, tissues, etc. are not cleaned thoroughly, the acidified water will be reduced to water when it encounters organic matter, and the disinfection effect will not be achieved

Abstract

A preparing device of binary medical sanitizer comprises a frame and a hydroxyl generator in the frame, and an anode and a cathode distributed in the hydroxyl generator, wherein the anode and cathode are respectively connected with a constant power supply. The anode has a catalyst layer coated and sintered on the TiO2 of anode base, and the surface of the TiO2 is coated and sintered with platinum, rhodium, or copper-ceria alloy as active catalyst material. The invention uses electric and particle effect to simulate the hydrogen and oxygen ions of water and the hydroxyl free group and oxygen free group of chloride ion to effectively kill the virus and bacterial of medical tool, to make tool clean and avoid cross transmission and infection of virus. When hydroxyl free group meets bacterial, the free group will directly break the cell membrane of bacterial to kill cell and decompose. And when the hydroxyl free group meets virus, it will directly solidify the protein of virus and inactivate the virus to kill the virus.

Description

technical field [0001] The invention relates to a preparation device for providing a harmless disinfectant to sterilize medical devices, in particular to a preparation device for a Gemini effect medical disinfectant, which can generate strong oxidants to completely kill viruses and germs remaining on medical devices , suitable for hand disinfection of gastroscope lenses, mirror tubes, surgical knife handles, surgical forceps and medical staff and non-disposable utensils. Background technique [0002] Existing medical sterilization methods are mainly divided into two categories: physical and chemical, of which physical sterilization includes: heat, ionizing radiation, microwave and so on. Chemical sterilants include: formaldehyde, glutaraldehyde, ethylene oxide, peracetic acid, hydrogen peroxide, etc. Physical sterilization is mainly aimed at some simple surgical instruments that are resistant to high temperature and high humidity. However, existing medical instruments often...
